Coolant HFE-SWA

Description

A high quality low oil semi-synthetic, chlorine-free, bio-stable water-miscible coolant designed to
provide the user with a robust, long sump-life product that is compatible with a wide variety of
materials. It is highly tolerant of microbial contamination and rejects tramp oil very effectively.

It is boron-free, and secondary amine free.

Coolant HFE-SWA has a low oil content which makes it             particularly for grinding
applications.

It is suitable for use in a wide variety of water qualities, is low foaming and forms an
exceptionally stable emulsion. In particular, Coolant HFE-SWA has been
designed to cope with the problems caused in hard water areas by keeping scum formation
down to an absolute minimum. It is very stable in hard water.

Coolant HFE-SWA has been formulated with the operator in mind and as such is designed to keep
Bacteria levels very low.
